Orbital Angular Momentum (OAM): The quantised component of angular momentum arising from the spatial distribution and helical phase structure of an electron beam.

The orbital angular momentum is one of the fundamental quantum numbers of the electron, similar to spin, which describes the apparent rotation of the electron. However, OAM is rarely observable in ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

A research team succeeds in solving a decade-old physical puzzle: the question of the fate of angular momentum during the ultrafast demagnetization of nickel crystals by laser light.

Orbital-angular-momentum-encoded diffractive networks for object classification tasks ... OAM can carry spatial information such as an object’s position, arrangement, or structure.

Overlooked electron property opens up new avenues for orbitronics. The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220004 considers high frame-rate orbital-angular-momentum multiplexing holography.

First introduced nearly a century ago, the concept of spin angular momentum, or spin, is critically important in quantum physics and underpins the emerging fields of spintronics and quantum computing.

You can do a calculation of the angular momentum for something that genuinely is rotating-- an orbiting electron, say, or a spinning molecule-- and you find that "zero" is always among the allowed ...
